Re: Manganin coil Brige by Pye and Co
You are totally right, variable resistance box, I would have to add it in a tiny circuit, but you're right.
I'll try it this week, I'll get the room to 17 centigrade and it should give great accuracy.
I'm tempted to open it. Screws look untouched so maybe best left alone. The same goes for restoring the top, where it has lost some shine, due to use.
